fix(start): init user languages before wrapped redirect for new users

New users arriving via wrapped share link (t.me/ffmemesbot?start=wrapped)
had no user_language rows because handle_start returned early before
init_user_languages_from_tg_user. All recommendation engines INNER JOIN
user_language, so these users got 0 meme candidates → "мемы закончились".
